About this file
This document contains questions and answers from a pre-bid meeting for a federal-aid highway project. The project will rehabilitate 6.54 miles of Donner Pass Road in California, adding bike lanes, drainage improvements, signing, striping and guardrail. Significant work includes 7,500 cubic yards of roadway excavation, 195 cubic yards of rock excavation, 12,000 cubic yards of aggregate base, and 20,000 tons of asphalt pavement. The total estimated cost is between $10-14 million. Construction will take place from spring 2020 to fall 2021. Bidders must use a 4:1 formulation for Type L pavement markings within the project region. Recessed pavement markings and MMA should be installed at a minimum depth of 0.11 inches. The project will require 8.25 acres of upland seeding and 0.05 acres of wetland seeding. Alternative retaining wall systems may be considered after award through value engineering.

Questions Answers
1 Requesting clarification for bid item A2120 63402-2300
PAVEMENT MARKINGS, TYPE L, SOLID:
What is the required formulation for Type L Markings for the above referenced project (4:1) or (98:2)? Caltrans always requires
4:1 within this region as this is the most common equipment available for this region.
Use a 4:1 formulation.
2 For the blue this would have to be a 98:2 material as blue is not manufactured as a 4:1. Will Type D epoxy Paint or Preformed
Thermoplastic be acceptable for the 400 LF of Blue 4” Lines?
Yes, either would be acceptable. However, Paint is preferred to remain consistent with other longitudinal markings.
3 What is the required mill thickness for the Type L Pavement markings 60Mils, 90Mils, ETC
Install the pavement markings at 90Mils
4 Are the Type L Line being recessed and if So what is the required depth of the recess?
Recess depth should be a minimum of .11 inches.
