Drive the Project

Where to Start

Print out a copy of the estimate sheet and summary sheets (most current version).

Make sure you have a measuring wheel.

Take your updated Route Log.

Has your DMI been calibrated recently?

Before You Hit the Road

Measure the width in several locations per mile.

Don’t measure in curves, at mailboxes, or at entrances.

Note changes in Typical Section.

Drive the Project

Is there striping? Centerline, Edgelines, etc.

Are there manholes, and who are the owners?

Are there pavement markers to be removed?Only replace on Interstates, Parkways, and

TWLTL’s

Are there bridges or culverts?Check with bridge section.

Things to look for

EDGELINE RUMBLE STRIPS

CENTERLINE RUMBLE STRIPS

What types of shoulders are there?Are there drop-off that need correctingCan it be paved monolithic or separate

pavement wedge?

Is there curb and gutter?

Are there any RR Crossings?

Are there ADA compliant sidewalk ramps?

Things to look for

Does the project have thermo to be replaced?Include quantities on summary sheets.

Are there traffic or planning loops affected?Include quantities on summary sheets.

Are there base failures that need repaired?Include quantities on summary sheets.

Things to look for

How do you know if it’s a base failure?

Deep crackingRutting / pumpingWater / mud coming out of cracksUsually located near edge of pavement

Base Failures

What is this?

What to do here?

Used to correct out of section pavement.Correcting cross slopes, dips, etc.

Not a Scratch Course.

How much do you need?

Level and Wedging

Ride the project

Visual survey

Usually calculated as a percentage of surface quantity.

Calculating Leveling and Wedging

If the route needs more than 50% leveling and wedging, consider milling the entire route.

Helps to reduce pavement edge drop-offs.

Corrects existing rutting.

Re-defines pavement section.

How much is too much

At Bridge ends and RR crossings.Usually 100 feet per 1 inch.

Curb and Gutter sections

Alternative to leveling and wedging.

Make sure milling depth is appropriate.

Milling

TOO MUCH MILLING

Cross slope problems

Check intersections to see if needed.

Not for commercial entrances.

Include all bid items.

Is it technically feasible?If not, include documentation and pictures.

Sidewalk / Handicap Ramps

ADA ramp, what to do here?

Do you see anything wrong?

What to do here?

What do you see?

Input project data into estimate program.

Check all quantities for errors.

Verify pavement type against Warrants.

Pavement depth1.0”, 1.25” or 1.5” (District 1, 2, 3 only or SMA)

Back in the Office

Complete typical sectionsOne typical for each pavement section.Use common sense.

Show detailsPavement typeDepthType of shouldersMilling if required

Typical Section

What type is needed for this project?

Will night work or restricted hours be needed?

Are there dates where no lane closures will be allowed?Holidays, festivals, etc.

Will it be a significant project?Include Public Information Plan.Complete documents for TMP.

Traffic Control Plan

Check Diana’s “commonly made mistakes” email.Did you need flashing arrows or message

boards?

Did you include Fuel and Asphalt adjustments?

Use comments section.

Don’t forget!

Use Traffic Engineer to help with Thermo and Loop quantities and locations.

Check with Permits, Project Development, and HSIP Coordinator for conflicting projects.

Check with Bridge section if bridges are on the project.

Did you include all applicable notes?

Things to Remember

Did you miss anything?

See it from a contractor’s view?

What will the inspector see?

Is there anything unexpected that you may have missed?

Drive the project again
