This study demonstrates the use of Class F fly ash in combination with lime or lime kiln dust in the full depth reclamation (FDR) of asphalt pavements. FDR, in the context of this paper, is a process of pulverizing a predetermined amount of flexible pavement that is structurally deficient, blending it with chemical additives and water, and compacting it in place to construct a new stabilized ba...

This research intends to evaluate the effects of waste polyethylene terephthalate (PET), antistripping agents (ASA), and ground tire rubber (GTR) on performance properties stone matrix asphalt (SMA) mix binder/water damage resistance. Liquid agents, added 85/100 penetration grade binder ASA effects, were A (M500), B (EvothermM1), C (LOF-6500). Tests conducted study modified bitumen’s rheologica...

Waste cooking oil (WCO), in many cases, can rejuvenate aged asphalt and restore its properties. However, the influence of WCO qualities on rejuvenation behaviors of aged asphalt has not been investigated in detail. The objective of this paper was to evaluate the effects of WCO viscosity and acid value on the basic, rheological, and chemical properties of a typical rejuvenated asphalt. Penetrati...

Graphene Tourmaline Composite Micropowder (hereinafter referred to as GTCM) modified asphalt was prepared by the ball milling method. The effects of different temperatures and frequencies on high-temperature performance composite-modified were evaluated dynamic shear rheological test, viscoelastic properties under stresses analyzed. low-temperature GTCM-modified analyzed bending beam its mechan...

Rutting of asphalt pavement occurs earlier and is more serious under the increasingly heavy traffic load conditions that can be found in subtropical monsoon climate regions. High modulus concrete (HMAC) with excellent anti-rutting anti-fatigue properties generally used to mitigate this issue. Given relatively high cost additives type asphalt, study feasibility using recycled mixture (RAP) Trini...

The adoption of warm mix asphalt (WMA) technologies is well accepted due to its promising environmental benefits, however, their long-term field performance not understood. This study focused on the rutting resistance WMA and companion hot (HMA) based 83 samples collected from 28 projects across United States covering four climate zones, quantified impacts for various as compared HMA. Field cor...
