About this file
This is a technical specification document for bituminous concrete paving work prepared for the Municipal Authority of the Borough of Morrisville in Bucks County, Pennsylvania, in conjunction with a 2026 Design/Build Curb Ramp Project. The specification details the complete paving requirements including asphalt base course, binder course, wearing course, and tack coat materials, all conforming to Pennsylvania Department of Transportation (PennDOT) Superpave standards as outlined in Publication 408. The work encompasses asphalt paving of roadways with subbase course preparation using PennDOT No. 2A coarse aggregate, surface preparation including proof-rolling with a 10-ton roller, tack coat application, and multiple asphalt layers placed to specified compacted thicknesses. Environmental requirements specify that asphalt placement cannot occur when base surface temperature is below 40 degrees Fahrenheit or when the base surface is wet or frozen. All work must conform to the latest edition of PennDOT Publication 408 and applicable Borough standards for paving work on public property.
The specification establishes strict quality assurance standards requiring material certifications from bituminous and aggregate suppliers and compliance with PennDOT specifications. Tolerances are tightly controlled, with maximum flatness variation of 1/4 inch measured with a 10-foot straight edge, compacted thickness within 1/4 inch of design specifications, and elevation variation not exceeding 1/2 inch. The contractor is responsible for restoring any existing paving outside the work limits that is damaged by contractor operations. Joint preparation requires minimum one-foot cutbacks with straight joint lines and right-angle offsets, and completed joints must be sealed with hot bituminous material. Hand compaction is required in areas inaccessible to rolling equipment, and painted markings must be provided as shown on project drawings.

PART 3 EXECUTION
3.01 EXAMINATION AND PREPARATION
A. Verify gradients and elevations of area to be paved.
B. Trim existing paving with minimum one (1) foot cutbacks to remove damaged areas. Cut straight joint lines and right angle offsets.
C. Remove any temporary paving material.
D. Proof-roll subgrade (10 ton roller) and replace any soft or unsuitable material with coarse aggregate.
Verify compacted subgrade is dry and ready to support paving and imposed loads.
E. Apply tack coat in accordance with PennDOT Publication 408 requirements prior to placing an overlay over existing paving or prior to placing a wearing coarse over a previous placed binder course.
F. Coat surfaces of any manhole or catch basin frames with oil to prevent bond with asphalt paving.
3.02 SUBBASE COURSE
A. Place PennDOT No. 2A coarse aggregate in continuous layers not exceeding 6 inches loose depth, and compact (10 ton roller) to required contours and elevations.
3.03 PLACING ASPHALT PAVEMENT
A. Place bituminous concrete base course on surface of compacted subbase course to compacted thickness (10 ton roller where possible; minimum 5 ton roller in trenches) as shown on Drawings.
B. Place binder and wearing courses to compacted thicknesses (10 ton roller except minimum 5 ton roller for binder course in trenches) as shown on the Drawings. Apply tack coat on completed binder course before placing wearing course should there be a delay between completion of binder course and placement of wearing course.
C. Place wearing course overlay to compacted thickness (10 ton roller) as and where shown on the Drawings.
D. Compact pavement by rolling to achieve even and smooth finish, without roller marks. Hand compact in areas inaccessible to rolling equipment.
E. Where proposed asphalt paving adjoins existing asphalt paving, seal the joint with hot bituminous material in accordance with PennDOT Publication 408 requirements.
F. Provide painted markings where shown on Drawings.
3.04 TOLERANCES
A. Flatness: Maximum variation of 1/4 inch measured with 10 foot straight edge.
B. Compacted Scheduled Thickness: Within 1/4 inch of design thickness.
C. Variation from True Elevation: Within 1/2 inch.
