Fatigue cracking of viscoelastic asphalt composite materials is one the major distresses in pavements. To quantify weakening effect fatigue cracks on mechanical properties materials, this study takes an asphalt-filler system as example, and micromechanics models are proposed by combining Eshbely’s equivalent inclusion theory Mori-Tanaka approach. Dynamic shear rheometer (DSR) tests performed sy...

Newer technologies such as warm mix asphalt (WMA) and reclaimed pavement (RAP) have gained international approval been considered appropriate solutions that support the sustainability goals of highway sector. However, both present some shortcomings. The lower mixing compaction temperatures WMA reduce binder aging bond between aggregates coating binder, thus resulting in less rutting resistance ...

The majority of recent research in has been focused on the introduction, development, and evaluation performance-based specifications for design asphalt concrete mixtures. In Caribbean, most laboratories only use Volumetric Marshall Mix methodology. Road designers, engineers, consultants, contractors have all highlighted many shortcomings inadequacies volumetric mix selection process. consensus...

Recent technological developments have attracted the use of machine learning technologies and sensors in various pavement maintenance rehabilitation studies. To avoid excessive road damages, which cause high costs, reduced mobility, vehicle safety concerns, periodic roads is necessary. As part works, conditions should be monitored continuously. This monitoring possible using modern distress det...

Abstract At the end of their service life, asphalt pavements exhibit distresses such as cracking and ravelling due to aged bituminous binder. The recycling process reclaimed should compensate for deteriorated binder properties. main objective this study is compare two common strategies: use a softer rejuvenator. Three percentages, 0%, 40% 70% were evaluated. All blends prepared with similar pen...

The municipal street network acts as a multifunctional asset by providing people, vehicles and public services with well-functioning infrastructure. To keep it in good condition, optimal maintenance measures are required which would result an efficient use of taxpayers’ money. This paper investigates the deterioration processes management practices that administrations have applied Sweden. stud...

Rutting is one of the significant distresses in flexible pavements. Examining methods to decrease permanent deformation considerable importance provide long service life and safe highways. The main objective this paper undertake a state-of-the-art review combine existing work on asphalt concrete For purpose, synthesizes evolution models, tests used evaluate quantify rutting potential mixtures w...

In this paper, we compared five crack detection algorithms using terrestrial laser scanner (TLS) point clouds. The methods are developed based on common cloud processing knowledge in along- and across-track profiles, surface fitting or local pointwise features, with without machine learning. area volume were calculated from the points detected by algorithms. completeness, correctness, F1 score ...

One of the important aspects highway design is aggregates. Aggregates strength and consistency has an effect on pavement structure’s overall performance. The base material near site construction doesn’t always match requirements carrying quality aggregate raises cost construction. Stabilizing agents such as asphalt cement, lime, fly ash were used to improve these materials in order make greater...
