Abstract

This project encompasses the design, schedule and budget of a recycled asphalt driveway located on a vineyard in San Luis Obispo County. The design parameters that served as the basis of this project were provided by Mr. Jean-Pierre Wolff of Wolff vineyards. He owns and operates a local winery on the outskirts of San Luis Obispo. He implemented a similar upgrade on his own winery. The purpose of these road improvements was to improve the conditions for the grapes as well the air quality for visitors to the winery. The new road needed to be wider and more suitable for all weather conditions than the existing road. A wider road made the vineyard more accessible for large delivery trucks and large equipment. A width requirement and all-weather surface road is also enforced by the California Dept. of Forestry (CALFIRE) and county fire requirements. As mentioned in Article 2 Summary of Fire Safe Regulations Title 14 Code of California Regulations: Division 1.5, Chapter 7, Subchapter 2, Articles 1-5, CALFIRE of the mandates that any access road must be at least 18ft wide and be an all-weather surface for access in the event of an emergency. The design of this road was completed in AutoCAD. This program provided a 2-D cross sectional model of the road. Cross sections are the most efficient way to convey a design scheme for this application. The dimensions used in this design fit all the parameters that were set by Mr. Wolff and CALFIRE. A 3 to 6 inch base layer would cover the existing roadway and have a width of at least 18 feet. The 3” top layer of recycled asphalt is placed on top of the base material. Swales and drainage systems will be installed where necessary. If this design were to be implemented it would increase the quality of the environment of
