The influence of waste cooking oil (WCO) on the performance characteristics of asphaltic materials indigenous to Trinidad, namely, Trinidad Lake Asphalt (TLA), Trinidad Petroleum Bitumen (TPB), and TLA : TPB (50 : 50) blend, was investigated to deduce the applicability of the WCO as a performance enhancer for the base asphalt. The rheological properties of complex modulus (G (∗) ) and phase ang...

The utilization of reclaimed asphalt pavement (RAP) contributes significantly to reducing resource waste and protecting the environment. However, due performance rejuvenator, fatigue cracking has always been one important constraint on development pavements. Based studies previously conducted by our group, this paper investigated properties rubber/oil (WRO) rejuvenated common dynamic shear rheo...

During the last decades, extensive research has been carried out on using reclaimed asphalt pavement (RAP) material in production of hot recycled mix asphalt. Unfortunately, aged, stiff, and brittle binder RAP typically increases mixture stiffness can therefore cause fatigue low-temperature damages. In scientific literature, there are many studies concerning aging rejuvenation bitumen, but is a...

The European Union is promoting a circular economy in which waste management plays an essential role. Although many studies focusing on the use of recycled materials manufacture asphalt mixtures for roads have been developed, related to construction bike lanes are scarce. In this context, main objective research explore behaviour with high replacement rates materials—reclaimed pavement (RAP) an...

One of the challenges using recycled materials in road structures is to maintain safe and durable pavements. A multitude research has been conducted over years on various materials, with a focus structural performance Another crucial, but almost overlooked, aspect pavement’s ability provide adequate skid resistance for users under different climatic conditions. With this mind, present study aim...

The application of recycled aggregates in the asphalt industry has been investigated recent decades. However, low percentages these materials have practically used mixtures because limitations set by relevant specifications due to their performance uncertainties. This research investigates feasibility increasing percentage 100% hot mix (HMA). Recycled concrete aggregate (RCA), glass (RG), and r...

This study investigated the effect of distribution aged binder from reclaimed asphalt pavement (RAP) on fracture tolerance recycled mixtures. Two RAP sources (one coarse, one fine), virgin polymer-modified binder, and four contents (0 %, 20 30 40 %) were used to produce a total seven Fracture was assessed in terms energy density (FED) at three levels: interstitial component (IC) (composed effec...

In this work, an aged asphalt was mixed with a new modified based on styrene–butadiene–styrene (SBS) in different proportions, and the warm mixing agent added to simulate fusion behaviour recycled fertilizer (reclaimed pavement, RAP) content. Low field nuclear magnetic resonance (LF-NMR), atomic force microscopy (AFM), Fourier transform infrared spectroscopy (FTIR) were used as analytical techn...
