Filter by Keyword44 report(s) found with pavements in the keywords field This study aims to investigate the age-dependent changes in flexural and fracture properties of fiber-reinforced concrete (FRC) used in the design of thin overlay pavements. Four different types of steel or polypropylene macro-fibers with different dimensions and different fiber volume contents (0%... Conventional test methods for roadway compaction cover less than 1% of roadway; whereas, intelligent compaction (IC) offers a method to measure 100% of a roadway. IC offers the ability to increase compaction uniformity of soils and asphalt pavements, which leads to decreased maintenance costs and an... North Dakota currently designs roads based on the AASHTO Design Guide procedure, which is based on the empirical findings of the AASHTO Road Test of the late 1950s. However, limitations of the current empirical approach have prompted AASHTO to move toward the new mechanistically based pavement design... Field samples were obtained from cores taken from multiple roads around the Salt Lake Valley in Utah and prepared for BBR testing. The response of field cores showed that even though the same binder grade used in the region was the same, the resulting mixtures have significant differences in creep moduli... This study addresses both structural and surfacing issues associated with unpaved roads subjected to heavier traffic applications. Different gravel types with various dust suppressants including recycled asphalt pavement (RAP) and soil stabilizers were evaluated in an attempt to provide the best road... As more Recycled Asphalt Pavement (RAP) becomes available to use in roadways, The Wyoming T2/LTAP Center and two Wyoming Counties investigated the use of RAP in gravel roads. The Wyoming DOT and the Mountain-Plains Consortium funded this study. The investigation explored the use RAP as a means of dust... In this paper, elevator trip generation equations are estimated from detailed facility, land-use, and highway traffic data in North Dakota. A trip attraction equation is used to explain the effects of elevator storage capacity and side track capacity on elevator throughput. Elevators are classified on... This report is Phase II of a previous MPC research project (MPC 02-136) that developed a computer model using a transient, two-dimensional finite volume approach to mathematically describe the thermal response of asphalt pavements due to thermal environmental conditions on an hourly basis. The main objective... This research evaluates the effectiveness of hot-poured crack surfacing material and its ability to seal asphaltic cracks. The term "crack surfacing" is used to describe the rigidity of the material and to distinguish it from crack sealants. The University of Wyoming, in cooperation with the Wyoming... Coal ash is the portion of ash rejected by the stack and collected at the base as a waste product. Coal ash is comprised of bottom ash and fly ash. Fly ash accounts for 70 percent to 80 percent of total coal ash and the rest being bottom ash. Only 39 percent of bottom ash is utilized with the rest being... |
