GlasPave Outperforms Others

BACKGROUNDEvaluating asphalt interlayers’ reflective crack performance in the field is typically an extremely time-intensive process, sometimes taking years to complete. Numerous studies and experiments, conductedby academia, government agencies, and the industry, have failed to create a reliable and inexpensive method. OBJECTIVEThe Texas Transportation Institute (TTI) performs overlay testing on its own asphalt mixtures to quantify the fracture performance of its asphalt. TTI sought to create …

NCAT – Effect of GlasPave in RAP

Problem Statement The geosynthetic material GlasPave™ has been effectively used at the bottom of asphalt surface layers to help mitigate the potential for thermal and stress-related cracks. However, there is concern regarding whether or not pavements containing GlasPave can be recycled. Specifically, will reclaimed asphalt pavement (RAP) material containing milled-up GlasPave affect the performance properties of asphalt mixtures containing the RAP? Objective This study by …

The Smart Maintenance Strategy

Paving fabric is a long-lasting, economical choice for road repair This newly released work is a comprehensive study of pavement repair materials and methods. Itexamines maintenance treatments on 370 roads in Greenville County, S.C., in the 1997-98 maintenance year. The work is called The Study of Pavement Maintenance Techniques Used on Greenville County Maintained Roads. Released in June 2005, it was performed by C. Joel …

Paving Fabrics – Are They Right For Your Project?

Water, Water, EverywhereThe major cause of Roadway deterioration is water beneath the pavement. The source of the water can be either rainfall or irrigation. Water softens the subgrade and typically reduces pavement structural capacity by about 60%. A pavement, which is saturated as little as 10% of the time, will only have 50% of the life of a pavement with a dry base. Most of …

Paving Fabric Interlayer as a Moisture Barrier

Paving fabric interlayer systems have been used in more than 230,000 lane-kilometers (142,000 lane-miles) of pavement in the U.S. Paving fabrics are a special class of geosynthetics which provide the generally acknowledged functions of a stress absorbing interlayer and a waterproofing membrane.1 The stress related performance has been easily verified by the observed reductions of cracking in pavement overlays. The waterproofing benefit is not easily …

Paving The Way at Indy

Mecca of U.S. automobile racing, the Indianapolis Motor Speed­way was initially surfaced in 1909 with a mixture of crushed stone and tar. However, the track soon began to disintegrate as speeds exceeded 70 miles an hour, and up to 20 cars competed in the longer events of 300 miles. To prevent further problems, more than 3 million bricks, grouted in cement, were installed on the …

Nonwoven Paving Fabrics Study Final Report

EXECUTIVE SUMMARY Under contract with the Geotextile Division of the Industrial Fabrics Association International, Maxim Technologies, Inc. investigated the use, performance, and design considerations for asphalt membrane interlayer systems utilizing a nonwoven paving fabric. This is a widely used technology with more than 15,000 lane miles installed each year in North America. Although performance of the system has obviously sustained this amount of annual usage, …

Evaluating the Cost-Effectiveness of Four Pavement Treatments

A study evaluating the cost-effectiveness of using paving fabrics in roadway maintenance projects is getting a new look. The original work was a comprehensive study of pavement repair materials and methods. It examined maintenance treatments on 370 roads in Greenville County, S.C.. in the 1997-98 maintenance year. Released in 2005. The Study of Pavement Maintenance Techniques Used on Greenville County Maintained Roads, was undertaken, compiled, …

SEW WHAT?

Berrien County just dropped a dress size. And a dress size means less fabric – except in this case. This time, we’re talking about road fabric. As one may guess, road fabric isn’t like silk or cotton or cashmere. It’s a waterproof membrane that’s placed in between hot mix asphalt layers to keep water from penetrating through. Road fabric is composed of a grid system …
