Overview of Permeable Bases
Drainable pavement systems consist of: permeable base, separator lyer, and edgegrain system. This paper focuses on permable bases. A permeable base must provide both permeability and stability....
Consistency and Fairness in Geotextile Specifications
By clearly defining required material properties in terms of 'Minimum Average Roll Values' for routine quality control tests and 'Average Test Values in the Weakest Principal Direction'...
Implementation of Material Requirements in Specifications
This paper focuses on where to find information on materials, their compatibility, minimum standards and specifying of materials and their use. The paper also presents case histories on...
Polyolefin Plastic Water Service Line Performance
Polyolefin (PO) plastic piping made from polyethylene (PE) and polybutylene (PB) materials have been used in diameters of about 1 in. for water service lines for buildings. Both PE and...
