Pavement Design Loading ESALS = Traffic Index or TI Soils (R-value) GE = 0. 0032 (TI)(100 -R) PAVEMENT BASICS

Pavement Deterioration Cycle PAVEMENT BASICS

Pavement Deterioration Asphalt concrete deteriorates in two ways: Oxidizing effects of sun and water PAVEMENT BASICS Fatigue from heavy wheel loads

The Impact of Heavy Loads PAVEMENT BASICS

What is a Traffic Index? The projected equivalent single axle loading that a pavement will experience over its design life PAVEMENT BASICS

PAVEMENT PRESERVATION PRINCIPLES

Applying the RIGHT TREATMENT to the RIGHT PAVEMENT at the RIGHT TIME using the RIGHT MATERIALS PAVEMENT PRESERVATION PRINCIPLES

Pavement Preservation Timing PAVEMENT PRESERVATION PRINCIPLES

Good Pavement Management • Best-First “Top Down” Management: focuses maintenance and rehabilitation on the best streets in the system. Interim procedure. • Worst-First “Bottom Up” Management: focuses maintenance and rehabilitation on the worst streets in the system. Interim procedure. • Critical-Point Management: focuses maintenance and rehabilitation on streets above rather than below a critical PCI. Most economical in the long run.

PROJECT SELECTION

Project Timing • Time of year • Proximity to schools • Day or night • Traffic control needs PROJECT SELECTION

Selecting the Right Streets • PMS data • Multi-year plan • Visual conditions • Grouping streets • Public input • Staff input PROJECT SELECTION • Budget • Utility coordination • Grants • Drainage • ADA

Selecting the Right Treatment Visually dividing your street list Project Street List Maintenance Streets Rehabilitation Streets • Environmental determination • Extent of loading failures • Extent of ADA improvements • Physical testing to determine structural adequacy • If adequate, consider maintenance option PROJECT SELECTION

R-Value Design PAVEMENT EVALUATION AND TESTING

Design Considerations • Previous overlays / existing crown • Road improvements • Shallow utilities PAVEMENT EVALUATION AND TESTING

Design Considerations for Sustainable Options • Cold-in-place recycling (CIR) • Pulverization and resurfacing / full-depth reclamation (FDR) • Milling and resurfacing requirements PAVEMENT EVALUATION AND TESTING

Cold In-place Recycling • Pavement must be structurally adequate. • Pavement must have a minimum HMA layer thickness. • Pavement must have a minimum existing base of 10 inches if R-value is less than 30. • CIR depth cannot extend to base layer. Why? • 1. 75 to 2. 50 -inch cap is not sufficient if a pavement is structurally deficient (may not meet HMA design). • A minimum depth ensures good CIR layer (3 -4 inches). • A minimum base thickness ensures heavy equipment doesn’t destabilize the grade. PAVEMENT EVALUATION AND TESTING

Pulverization and Resurfacing/FDR • • The preferred Traffic Index (TI) should be less than 7. 0. Pavement must have a minimum aggregate base of 12 inches or an R-value less than 30. Pavement must have a minimum aggregate base of 9 inches or an R-value greater than 30. Check crown. Why? Typical build-up is not feasible over 2 to 3 inches unless there are no vertical constraints. Pulverizing, grading and compacting will destabilize a grade if the R-value and corresponding base thickness do not meet minimums. The intent of pulverizing is to create a new aggregate base section. Generally, limiting the off-haul of the pulverized base is important to ensure a sufficient structural section. PAVEMENT EVALUATION AND TESTING

Milling and Resurfacing • Pavement must be structurally adequate or only slightly deficient. • Pavement must have a minimum existing HMA depth of 5 inches. Why? • Milling reduces the in-place structural capacity and requires some replacement value. If the pavement is structurally deficient, the mill depth typically becomes excessive. • A minimum layer thickness is necessary to ensure milling equipment and loaded trucks do not break through the existing HMA.

COST ANALYSIS LIFE CYCLE COST ANALYSIS (LCCA)

COST ANALYSIS

Develop and Evaluate Recommendations Short-term pavement rehabilitation options These options are not available for this street because of structural deficiencies and/or pavement cracking condition. COST ANALYSIS

Develop and Evaluate Recommendations Long-term pavement rehabilitation options Overlay Option: RHMA For option 1, we recommend 4 -inch digouts for base failures, placing a 1/2 inch HMA leveling course and a 1 -3/4 inch RHMA overlay. Estimated Cost: $241, 000 COST ANALYSIS Estimated Life Expectancy: 10 -12 Years

Develop and Evaluate Recommendations Long-term pavement rehabilitation options Overlay Option: HMA An overlay using HMA is not recommended because the 3 -3/4 inch structural requirement exceeds the 3 -1/2 inch maximum overlay that is considered feasible to meet geometric constraints. COST ANALYSIS

Develop and Evaluate Recommendations Long-term pavement maintenance options Recycle and Mill and Replace Options These options are not available for this street because of the structural deficiencies and thin pavement layer. COST ANALYSIS

Develop and Evaluate Recommendations Long-term pavement rehabilitation options Reconstruction Option 1 For option 1, we recommend removing the pavement to a depth of 10 -1/2 inches and placing 10 -1/2 inches of new HMA. The HMA should be placed in 4 lifts. Estimated Cost: $631, 000 COST ANALYSIS Estimated Life Expectancy: 20 Years

Develop and Evaluate Recommendations Long-term pavement rehabilitation options Reconstruction Option 2 For option 2, we recommend removing 4 inches of the existing structure, lime treating the native soil and aggregate base to a depth of 13 inches and placing 4 inches of new HMA in 2 lifts. Estimated Cost: $292, 000 COST ANALYSIS Estimated Life Expectancy: 20 Years
