To investigate the trend of functional groups of matrix asphalt, styrene butadiene styrene ( SBS) modifiers, and their modified asphalt with aging time, and to analyze their aging modes. Using Fourier transform infrared spectroscopy (FTIR) and bending beam rheometer (BBR) tests, low-temperature performance tests were conducted on two types of asphalt binders aged for 0, 1, 5, 8, 24, 48, 72 h. Functional group analysis was conducted with SBS modifier to establish the relationship between the functional groups of the two asphalt binders and their low-temperature performance. The results show that SBS modifier aging are contributed by polybutadiene and polystyrene, the SBS modifier aging mode is degraded mainly alkene and alkane in the thermal oxidation process. Two kinds of asphalt binders aging mode are volatilized light oil and reacted with oxygen to form a cross-linked. The trend of SBS modifier at the characteristic peaks in infrared absorption spectra is different and independent of its modified asphalt. Two kinds of asphalt binders carbonyl index is correlative with creep compliance derivative, and low-temperature deformation capacity of asphalt binder is reflected by carbonyl index.

Two composite modified asphalts were prepared using different plasticizer: dioctyl phthalate (DOP) and dioctyl adipate(DOA) basing on SBS modified asphalt. Through asphalt basic index, dynamic shear rheometer, multiple stress creep recovery, bending beam rheometer and fourier transform infrared spectroscopy(FTIR) tests, the high and low temperature performance and anti-aging capability of two composite modified asphalts were comprehensively studied before and after aging, and being compared with SBS modified asphalt・ Two high temperature grades of SBS modified asphalt can be reduced by adding plasticizer that resulting in the rutting resistance decrease and irrecoverable deformation increase・ The low-temperature deformation and retarding pavement cracking capacity of SBS modified asphalt is improved by adding plasticizer. The performance difference of SBS modified asphalt with plasticizer before and after aging is obviously reduce・ Physical cross linking reaction being reacted between SBS modified asphalt and plasticizer is reflected by FTIR, the anti-aging capability of SBS modified asphalt is enhanced by adding plasticizer basing on sulfoxide index and characteristic peak area.

Scenario simulation and prediction of future land use is an integral step in ensuring regional sustainable development. The Markov chain was adopted to predict the total area of various types of land use in 2030. As envisaged in the 14th Five-Year Plan for Guangzhou Transportation, the PLUS model was used to simulate the land use pattern of Guangzhou in 2030 by setting up natural development and traffic planning scenarios. Additionally, the land use transfer matrix and landscape index were applied to explore the properties of land use type transformation and landscape pattern under two different scenarios. The results show that traffic planning has a significant impact on the artificial surface, within 3 km of traffic line，with the area of the artificial surface under the traffic planning scenario increasing by 22.06 km2 compared with the natural development scenario, which mainly transferred from cultivated land and forest land. The artificial surface will mainly undergo extensive expansion under these two scenarios. In the natural development scenario, the spreading speed of the artificial surface in each region will be relatively consistent, while in the traffic planning scenario, the artificial surface will be concentrated in the periphery of the central urban area, and the probability of distribution far away from the city center is low. Compared with natural development scenario, traffic planning scenario has higher patch dominance and more complicated patch form, which is reflected in the artificial surface with significantly increased dominance and cultivated land and grassland with more fragmented and complex shapes. Thus, it is reasonable to utilize the PLUS model to simulate the future urban land use pattern by considering transportation planning, since the simulation results can provide essential data support and decision-making bases to underpin future territorial space management and planning.

In order to study the effect of the replacement rate of recycled coarse aggregate, length-diameter ratio and diameter-thickness ratio on the axial compressive bearing capacity of middle long columns of recycled aggregate concrete with ferronickel slag filled steel tubes (RACFNSFST), the monotonic loading tests were carried out on eight RACFNSFST under axial compression. By comparing the calculation method of axial compressive capacity recommended by the domestic and foreign common concrete-filled steel tube codes, the prediction formula of axial compressive capacity is fitted by regression and compared with the test results. The results show that local buckling occurs at both ends of the medium and long column, which is the failure mode of material, and the long column is the failure mode of whole instability. The medium and long columns with the same reclaimed coarse aggregate substitution rate and section size have better bearing capacity and slower deflection growth than that of the long columns. With the increase of diameter-thickness ratio, the bearing capacity and ductility are reduced, and the hoop effect of steel tube on recycled concrete is obvious. The fitting formula is simple and practical, and it is in good agreement with the measured value. [ABSTRACT FROM AUTHOR]

The growth, survival rate, serum immunity and antioxidant enzymes, and economic benefits of Oplegnathus punctatus (350. 6±24. 3 g) reared in recirculating aquaculture system and offshore aquaculture net pen were investigated to evaluate the technical feasibility of the land-sea alternate mariculture model for Spotted knifejaw,Oplegnathus punctatus. Results showed that the average individual weight of Oplegnathus punctatus reached (547. 6±25. 2) g and the survival rates reached 95. 8% in the recirculating aquaculture system,while the average individual weight of Oplegnathus punctatus reached ( 735. 7 ± 27. 9) g and the survival rates reached 98. 3% in land-sea alternate aquaculture after 120 days culture. The contents of serum lysozyme (LZS),superoxide dismutase ( SOD),glutathione peroxidase (GSH-Px) and catalase ( CAT) in land-sea alternate aquaculture were significantly higher than those in recirculating aquaculture system (P<0. 05),40. 5%,43. 2%,42. 3% and 39. 8%,respectively. In addition,the net profit of land-sea alternate aquaculture was 128. 34% higher than that of recirculating aquaculture. The results indicated that the optimal growth performance, strong immunity, antioxidant activities and high economic benefits of Oplegnathus punctatus were obtained under the land-sea alternate aquaculture model,which provides the theoretical basis and data support for land-sea alternate aquaculture of Oplegnathus punctatus.
