WAPA Asphalt Design Competition by val48728


									                     2009 WAPA Asphalt Design Competition
The WAPA Mix Design Competition has evolved into the WAPA Asphalt Design Competition. The
WAPA Asphalt Design Competition expands the asphalt engineering beyond just the HMA mix
design to include pavement structure design and project management engineering. The competition
consists of establishing a pavement construction scope, determining a pavement structure,
developing a HMA mix design, planning out the construction process and summarizing all of this
engineering into a unit price and project cost estimate that your project team is submitting as a
construction bid.

Currently there is not a National Competition with a similar structure, so WAPA is modifying
the competition award structure.

           1st Place $1000 to the Team*
           2nd Place $500 to the Team*
                     $100 to each other Team*

           *A team must earn a minimum of 75 points
           to be eligible for prize earnings.

The competition is open to the following schools:
         Marquette University
         Michigan Technical University
         Northeast Technical College
         University of Wisconsin - Madison
         University of Wisconsin - Platteville

The competition team can be composed of undergraduates and graduate students, however
the team will be accessed a 5 point deduction for each graduate student member.
The competition team is limited to a maximum of 5 members.

2009 competition aggregate materials were supplied by Mathy Construction.

An additional competiton format change is the elimination of the video presentation submission.
The new format requires the submission of HMA superpave gyratory compaction specimens,
gyratory compaction data, a written report and PowerPoint presentation and a "live" presentation
to the competition judges via web conferencing and conference calling.

                                            Project Data
Project Information:
                Highway:     STH 1000
                Location:    Town of Wapaville in Blacktop County, Wisconsin
          Project Length:    6.8 miles (Rural highway with no connecting sideroads or field entrances)
           Project Scope:    2-Lane Roadway Pavement Replacement (20 year minimum service life desired)
                             Traffic growth on this section of roadway has exceeded original design parameters.
                             Pavement replacement is required to properly address traffic growth. This segment of highway
                             has a 3% longitudinal grade with gentle side slopes and 100 feet of right-of-way on each side of
                             the roadway centerline. The roadway profile may be raised a maximum of 24". The new pavement
                             is to be 30' paved surface (two 12' lanes and two 3' paved shoulders) with a normal (2%) crown.

                             Existing pavement history:
                                               1975 Original Construction
                                                     22' pavement width, with a 1% crown
                                                     Pav't Structure:
                                                                 4" HMA
                                                                 12" CABC
                                               1995 Pavement Rehabilitation
                                                     3" HMA Overlay (1% crown maintaned)

                                        Current pavement distress survey shows that a typical 500' survey section
                                        contains 30% alligator cracking on a square foot basis.

Pavement Structural Design:
                  Traffic:   2,800,000 Total 20-yr Design ESALs
                    Soils:   Well drained soil classified as A-4 (AASHTO classification)
                 Climate:    Wapaville Wisconsin has simlar climate conditions as Wausau Wisconsin.
          Design Method:     This project is part of a department research project and the pavement structural design
                              methodology is at the pavement designer's discretion (you may use whatever method you like).

Job Mix Formula Design:
                   JMF: Following WisDOT HMA pavement construction guidelines, the HMA pavement structure consists of two mix
                         designs (a lower layer mix and a surface mix). For the WAPA Asphalt Pavement Design Competition,
                         develop an appropriate job mix formula (JMF) for the surface layer that meets WisDOT specifications.
            Aggregates: For this project, there are three possible aggregates sources:

Construction Management:
                  Scope: Calculate a unit (TON) bid price for all of the HMA pavement mixture (assume the lower layer cost is the same as
                         the upper layer) that includes QMP Mixture, QMP Nuclear Density and QMP Ride (all of which are incidental
                         to the mixture), general overhead and profit. Develop a QMP Mixture testing plan, a QMP Nuclear Density testing plan
                         and a Construction Schedule for paving.

    Contract Parameters: Contract allows for 60 Contract Days for all pavement layers of HMA paving.
                         All paving must be done between 7:00 AM and 7:00 PM.
                         No work allowed on Sunday.
                         Work zones are limited to 2 miles in length.

                Facilities: HMA plant will be located at the selected aggregate source location.
                            HMA plant will be solely designated for this project.
                            Normal plant capacity is 350 tons per hour.

                   Labor: All labor (plant operator, plant end loader operator, QMP technicians, paving crew members, roller operators, trucking)
                          is at a rate of:
                                       1st 40 hrs per week       $35.00 per hour (includes time, materials, equipment)
                                       Hours beyond 40/week $42.00 per hour (includes time, materials, equipment)
