The accumulated irreversible deformation in pavement under repeated vehicle loadings will cause fatigue failure of asphalt concrete. It is necessary to monitor the mechanical response of pavement under load by using sensors. Previous studies have limitations in modulus accommodation between the sensor and asphalt pavement, and it is difficult to achieve the distributed monitoring goal. To solve...

Stone mastic asphalt (SMA) is a gap graded mix which categorised by more quantity of coarse aggregate, high content and fibre. Due to stone on contact presences filler content, it acts as stiff matrix reduces the rutting due heavy traffic load. This research presents study fatigue performance RAP replaced SMA mixes using VG 30 binder along with elastomer modifier results were compared conventio...

This paper wants to raise awareness of LCA/CF tools that have been built within European projects in the last 5-6 years and that are freely-available on the internet: asPECT, ECORCE M and CARBON ROAD MAP. The tools will be compared in terms of their architecture and system boundaries considered, as well as on the basis of the results of a comparative carbon foot printing exercise of several hig...

This paper describes the Accelerated Testing with the LINTRACK-facility of the innovative ‘Rollpave’ test pavement that was developed within the theme ‘Modular Pavement Structures’ of the project ‘Roads for the Future’ of the Dutch Ministry of Transport, Public Works and Water Management. The concept of ‘Rollpave’ is a thin pre-manufactured asphalt wearing course that is rolled on a reel. On si...

Committed to converting the Port of Balboa into a major transshipment hub, Panama Ports Company (PPC) launched in 2006 a $300-million expansion program to increase berthing and stacking space that would almost triple the port capacity. The site’s history of marine-related activities, deteriorating facilities, buried structures, and poor soils mandated significant investment in clearing and prep...

The durability of asphalt mixtures against floodwater immersion can serve as a reference to anticipate potential road damage. Moreover, Reclaimed Asphalt Pavement (RAP) materials have been discovered substitute for aggregate in pavement due their environmental friendliness and cost-effectiveness. Therefore, this research aimed assess the produced using RAP 1, 2, 4, 8 days. process involved Ston...

This study examined the long-term effectiveness of permeable pavement as an alternative to traditional impervious asphalt pavement in a parking area. Four commercially available permeable pavement systems were evaluated after 6 years of daily parking usage for structural durability, ability to infiltrate precipitation, and impacts on infiltrate water quality. All four permeable pavement systems...

The three major distress conditions affecting the performance of asphalt pavements are permanent deformation or rutting, fatigue or load associated cracking, and low temperature or thermal cracking. In an earlier technical topics article (Fall, 1998), we examined the causes of fatigue cracking and the importance of good compaction during construction to help minimize this type of distress. In t...
