Summary
Attachment B Standard Plans is a technical specification document from Oregon Department of Transportation providing standard construction details for asphalt concrete pavement (ACP) work. The document, designated RD610, establishes methodologies for pavement feathering, edge detailing, and matching existing asphalt pavement at project endpoints and bridge transitions. The specifications include two primary construction methods (Method A and Method B) with varying taper lengths based on posted speed limits, ranging from 1 inch per 50 feet for speeds of 45 mph or greater to 1 inch per 100 feet for higher-speed corridors. The standard drawing became effective June 1, 2023, with a revision date of November 30, 2023, and requires all materials and construction practices to comply with current Oregon Standard Specifications and generally accepted engineering principles. The document is intended for use by registered professional engineers and should not be implemented without appropriate professional consultation.
The technical specifications detail procedures for cold planing pavement removal, inlay surfacing techniques, and edge detail requirements for asphalt concrete base courses and wearing courses. The document includes provisions for both feathered and non-feathered construction methods, with specific guidance on handling existing gravel surfaces and variable aggregate base thickness ranging from 2 inches to 0 inches. These standard drawings serve as the baseline technical reference for state-funded pavement projects in Oregon and establish uniform construction quality standards across transportation infrastructure improvements throughout the state.
