To explore the effect of UV-curable polyurethane (UV-PU) on self-healing performance (SHP) asphalt and mixtures, this article conducted research in area evaluation method influenced law. (PU), Styrene-Butadiene-Styrene Block Copolymer (SBS Ι-C) 70# mixtures were introduced as example comparison. A for evaluating SHP asphalt, sand mixture, medium particle mixture using healing index (HI) an was ...

in this study, different contents of nano-silica, 2 wt.%, 4 wt.% and 6 wt.%, have been added to bitumen tomodify the physical, mechanical and rheological properties of warm mix asphalt (wma). wma iscontaining 2 wt.% of sasobit (mixture of long-chain hydrocarbons). various quality control tests have beencarried out to characterize the modified bitumen and wma. the rheological investigations show...

The establishment of a dielectric model the asphalt pavement surface material is premise and key to applying electromagnetic wave technology nondestructive testing. Asphalt can be made different materials, including various types mixtures. Therefore, in order study analyze properties mixtures establish material, this paper studies four commonly used course. Based on comparative analysis three c...

A laboratory study was made of the effects of crushed particles, both coarse and fine aggregate, on the stability of bituminous-aggregate mixtures. Crushed limestone and varying percentages of crushed and uncrushed gravel were used as the coarse aggregate while variation in the shape of the fine aggregate was obtained by using rounded natural sand and crushed-stone sand. These aggregates were u...

This paper analyzes how feasible it is to use electric arc furnace slag as coarse aggregate, and blast furnace dust as fine aggregate in the manufacture of hot asphalt concrete for roads. Three mixtures were designed using the Ramcodes methodology, the M1 mixture of control with conventional materials, the M2 mixture replacing 50% and the M3 mixture replacing 100% of the conventional aggregates...

The anisotropy refers to the material properties that are direction dependant. In the past, the HMA has been typically modeled as an isotropic material due to a lack of sufficient data for detailed quantification of its direction-dependency. However, it is reasonable to assert that HMA may exhibit significant anisotropic behaviour due to the major compaction direction and the resulting preferre...
