Research of Mechanical Properties of Asphalt Pavement Materials with WMA and RAP Baoyang Yu 1, a, Yu Wang 1, b, and Minjang Zhang1, c 1 College of Civil Engineering, Shenyang Jianzhu University, Shenyang, 110168, China P.R.
Engineers can use this graph to evaluate different kinds of asphalt mixtures based on the E* result by comparing the rutting depth with E*.
Thus, engineers can design an appropriate pavement for rutting resistance using a specific.
Tensile strength testing result for porous asphalt mixture at 24°C Conclusions This study integrated three innovations in the pavement engineering field that could added credit to the LEED scoring system: asphalt pavements, warm-mix asphalt (WMA), and recycled materials.

The Effect of Compactive Efforts on the Hydraulic Conductivity Behaviour of Oil Contaminated Lateritic Soils Thomas Stephen Ijimdiya1,a and Friday Elaigwu2 1,2Department of Civil Engineering, Ahmadu Bello University, Zaria, Nigeria atom_ijim@yahoo.com Keywords: Oil contamination, Hydraulic conductivity, Compactive efforts, Permeability characteristics Abstract: Large quantities of oil contaminated soils result from pipeline vandalization, onshore and offshore oil spills every year in Nigeria.
It is in this vein that geotechnical engineers are faced with increasing challenges as a result of oil spills and hence the need for laboratory studies in order to develop methodologies for testing, identification, classification, engineering behaviour, stabilization, utilization and remediation technologies for such soils.
