      The researcher conducted the study in two phases; first phase was to test the rheological characteristics of the new product by using wet mix through dynamic shear Rheometer (DSR) and the second phase included preparation of ACW14 mixture containing base and modified bitumen by dry mix and testing them to determine fundamental properties (i.e.   The AASHTO Materials Standards contain specifications, test methods, and provisional standards commonly used in the construction of highway facilities. The Materials Standards are updated three times per year, in mid-April, mid-June, and mid-August. The April Update revises the sections on Hydraulic Cement and Lime, Fresh Concrete, Hardened.

      A new constitutive model for the asphalt concrete layer interface is proposed. Direct shear tests at four levels of normal load and three temperatures were performed on two types of asphalt concrete layer interface: with and without a tack by:   If water is present, the evaluation is in fact referred to as water sensitivity or moisture damage testing. Another distinction can be based on the type of sample that is evaluated. The test sample can be loose aggregates coated with a bituminous binder or a compacted asphalt mix sample.

It was estimated by Boorman in his book that ab, m 2 of “standard asphalt pavement” existed in the U.S. and 85 percent of this used Trinidad Lake asphalt as the binder. This roughly translates to about 2,, metric tons of equivalent hot mix (or about three times the annual amount of hot mix purchased by WSDOT).

Asphalt mix characterization using dynamic modulus and APA testing. final report summarizes two research efforts related to asphalt mix characterization: dynamic modulus and Asphalt Pavement Analyzer testing. One phase of the research consisted of a laboratory-based evaluation of dynamic modulus of Oregon dense-graded hot mix asphalt mixes.

Dynamic modulus (∣E∗∣) of hot-mix asphalt (HMA) mixtures is one of the fundamental engineering properties measured by the simple performance tester and has also been incorporated as.

The Asphalt Pavement Analyzer (APA) device was used to characterize the impacts of various mix factors on the development of permanent deformation dense-graded mixes. Factors investigated included: aggregate size of and 19 mm ( and in), VMA (high, design, low), fines content (design and high), binder content (low, design, high) and Cited by: 2.

Mixture performance tests were performed using an asphalt pavement analyzer (APA) and a retrofitted APA Hamburg test to determine rutting resistance. Moisture susceptibility was estimated by an indirect tensile strength test, and dynamic modulus (E*) was deteremined by asphalt mixture performance tester (AMPT).

To minimize this deterioration and it is necessary to pay extra attention to material selection and one solution is to formulate an asphalt mix that has a high physical properties and one way to do this is to use latex as an additive. The purpose of this experimental study was to investigate the effect of latex Author: Henri Siswanto.

The RAP mixture percentages used were 15%, 35%, and 50% in the study. The amount of RAP materials recycled within hot mix asphalt (HMA) drum plants are typically no more than 30% RAP.

Final report. (), by J. Sousa. The characterization provided the following: (1) mix modulus (stiffness) values at different temperatures, to be used in pavement design/analysis procedures, (2) rutting performance at intermediate and high temperatures, and (3) low-temperature thermal cracking performance.

The scope of the study covered two types of pavement material, three levels of oxydized condition of the old binder and one type of virgin.

Dynamic shear rheometer and bending beam rheometer tests. Dynamic shear rheometer (DSR) is considered as the stress used in determining the viscoelastic behaviors of binder at moderate to high temperatures.

DSR is used to measure complex shear modulus (G) and phase angle (δ). The asphalt is softer when the low complex shear modulus is Cited by: 2. A commonly used type of LWT, an asphalt pavement analyzer (APA), was chosen as a platform and modified to conduct the fatigue testing.

Introduction Asphalt mix is a heterogeneous material composed of asphalt binder, aggregates and air voids. Approx. 85% of the total volume of the mix is the aggregates, asphalt binder constitutes around 10% of the total volume and the rest is air voids (Mitra et al.
