One of the most critical problems in asphalt pavement construction today is achieving a long lasting longitudinal joint. It is costing pavement owners billions of dollars worldwide in premature repair of the joint. This problem has been recognized for a couple of decades discussed at many asphalt pavement seminars and has been the subject of

This results presented in this paper show the effectiveness of several new methods for determining the thickness of asphalt and concrete pavement for quality assurance of new construction. The accuracy objectives for QA particularly for pay factors produced a very demanding accuracy requirement 2.5 mm which has never been demonstrated previously with these methods.
here has been extensive research that shows that the life expectancy of asphalt pavement is highly dependent on uniform asphalt compaction. The widely accepted quality control metric for new paving is to drill core samples in the finished road and then measure their density in the laboratory.
Asphalt concrete commonly called asphalt blacktop or pavement in North America and tarmac bitumen macadam or rolled asphalt in the United Kingdom and the Republic of Ireland is a composite material commonly used to surface roads parking lots airports and the core of embankment dams. ...
Survey based on the condition of the existing concrete asphalt or composite pavement. A 3D Laser Condition survey is the process of collecting data to determine the structural integrity distresses skid resistance and overall riding quality of the pavement. A ...
In asphalt pavement construction it’s “compaction compaction compaction.” In this edition of the RoadReady newsletter we will focus on measuring the density of a pavement and therefore how well it was compacted as well as examining the challenges around to obtaining proper compaction.
GSSI’s New PaveScan RDM Asphalt Density Assessment Tool For testing asphalt density in real-time and non-destructively GSSI has just announced its new PaveScan RDM asphalt density assessment tool which provides accurate real-time measurements to ensure pavement life and quality.
Aggregates for Asphalt Concrete. The amount of aggregates for asphalt concrete mixtures is generally 90 to 95 percent by weight and 75 to 85 percent by volume. Aggregates are primarily responsible for the load supporting capacity of a pavement. Aggregate has been defined as any inert mineral material used for mixing in graduated particles or ...

Airoport infrastructure development requires care to maintain it in proper technical condition. Due to this airport pavements should be constantly monitored and above all correctly managed. High-level airport pavement management requires access to reliable information about their current technical condition as well as proper forecasting of this condition in the future. Obtaining good ...
The widely accepted quality control metric for new paving is to drill core samples in the finished road and then measure their density in the laboratory. The coring process besides being destructive typically takes days and the results from the lab are received long after the pavement has cooled and there is any chance of taking corrective action if problems are found.
Asphalt Pavement Scanner C. Oden October 2020 Introduction The ESS Asphalt Pavement Scanner APS is a revolutionary new system that provides detailed and comprehensive quality information for new asphalt mats without the use of nuclear sources. To demonstrate these capabilities a short survey was made at a new subdivision under construction.
The performance of asphalt concrete pavements ACP is greatly related to the rate of rutting. Stone dust is mostly used as a filler in ACP. Bagasse ash being cementitious in nature and costless ...
From the GAP 2019 transportation conference proceedings: In “Design and Construction of Bases and Subbases for Concrete Pavement Performance” Shreenath Rao Hesham Abdualla and Thomas Yu P.E. use a mix of data and case studies to show the impact that the base/subbase has on increasing or decreasing the overall concrete pavement performance.
