Effect of Groundwater Table Rising on the Performance of a Swedish- Designed Gravel Road

Sweden has a wide network of gravel roads. When the water table levels rise during the freeze-thaw and wet seasons, the bearing capacity of the roads will decrease and rut depths increase. The road will suffer a small deterioration every time a...

The performance of a trial gravel road under accelerated pavement testing

This study presents the performance of a trial gravel road subjected to HVS (Heavy Vehicle Simulator) trafficking in a compressed time period. The road structure was constructed with 150 mm-thick aggregate base course, and 125 mm-thick sub-base...

Evaluating the dynamic stabilities of asphalt concrete mixtures incorporating...

This study aims at investigating the impact of recycling by-product plasterboard wastes (gypsum and bassanite) with asphalt mixtures by replacing partly the filler portion of the asphalt mixtures with pulverised plasterboard wastes in order to...

Review on the effect of gypsum content on soil behavior

Increasing the utilization of urban soil usage brings along very important problems to be addressed at the international level regarding the use of sulfate bearing soils as construction materials. After briefly exploring current research...

Cold recycling of asphalt at a central plant: follow up of test roads in Halland,...

Cold recycling of asphalt is a resource-saving technology because the materials do not need to be warmed up. Moreover, by using this technique, up to 100 per cent reclaimed asphalt concrete (RA) could be recycled. However, in order to achieve good...

Hot recycling of asphalt at a central plant: a general quality control process and long...

This notat aims to highlight the various demands on hot recycling of asphalt at a plant and to study how the recycled asphalt mixtures differ from the new one and how much asphalt granules that can be mixed without affecting the pavement performance...

What it takes to be successful in international programs?

The overall objective of the INCRIS project was to ensure that the cooperation capacities of the Ukraine's leading road research centre, the Shulgin State Road Research Institute (DNDI), were reinforced to both foster its integration into the...

Improving low-volume road construction and performance: Validity of using the heavy...

VTI notat 9A-2013 highlights the benefits of using the heavy vehicle simulator (HVS) in verifying the validity of the proposed design of roads before construction which in turn leads to more efficient and economical road constructions. Sweden has a...

Modelling the Decrease of Total Soluble Salts of Clayey Soils during Long-term Soaking

Presented in this paper is an experimental investigation into the effect of long-term soaking on the decrease of total soluble salts (TSS) contents and distribution of moisture for compacted clayey gypsiferous soil. Two types (A and B) of clayey...

Predictive Equation for Soaked CBR of a Clayey Gypsiferous Soil

Presented in this paper is an empirical equation modelling the effect of long-term soaking on strength characteristics of a clayey gypsiferous subgrade soil.The soil tested is a fat clay of CH group according to the Unified Soil Classification...

Effect of Long-Term Soaking on the Distribution of Moisture and Total Soluble Salts in...

Presented in this paper is a study of the effect of long-term soaking on the distribution of moisture hence on the dissolution of total soluble salts (T.S.S.) and its distribution along compacted CBR samples of gypsiferous soil.The soil tested is a...
