A COMPREHENSIVE UNDERSTANDING OF ASTM F2561-06 THE STANDARD PRACTICE FOR REHABILITATION OF A SEWER SERVICE LATERAL AND ITS CONNECTION TO THE MAIN USING A ONE-PIECE MAIN AND LATERAL CURED-IN-PLACE LINER

摘要

ASTM International, originally known as American Society for Testing Materials, was formed over a decade ago, when a forward-thinking group of engineers and scientists got together to address frequent rail breaks in the burgeoning railroad industry. Their work led to standardization on the steel used in rail construction, ultimately improving railroad safety for the public. According to the current "Regulations Governing ASTM Technical Committees," a standard is defined as, "A document that has been developed and established within the consensus process of the Society and meets the approval requirements of ASTM procedures and regulations."The ASTM F2561-06 is a standard practice for rehabilitation of a service lateral and effectively seals the main fitting that connects the lateral service pipe to the main pipe. The standard specifies a one-piece, air testable, Main and Lateral Cured-ln-Place Lining (MLCIPL) to be robotically installed from a city-owned mainline. The finished MLCIPL will create a structural lining that is continuous in length and extends from the main pipe up into the lateral pipe to a predetermined distance not-to-exceed 200 feet. The one-piece Main/Lateral lining will be leak-free, and will eliminate ground water infiltration and root intrusion. The renewal process is accomplished by non-invasive methods where no excavation is allowed.This paper will discuss technical procedures and material composition in accordance with ASTM F2561-06 and why understanding this standard is important to any agency using public funds for infiltration correction, root control and structural renewal of a collection system. Specific sections in this paper include a purpose statement for explaining the key components and benefits incorporated within that section.
