Scope
Task 1- Project Start Up
1.1 - Background Research
Time was allocated to data collection and background research in order to fully understand the physical conditions, regulations and other constraints.
1.2 - Material Consideration
At least three different types of local Flagstaff rock were considered along with different cement and aggregate types. The chsoe materials were Flagstone and QUIKRETE.
Task 2 – Creation of Samples
2.1 - Mixing
The concrete was composed of QUIKRETE 5000, a commercial grade blend for rapid high strength concrete composed of Portland cement, sand, aggregate or stone, AKKRO-7T a liquid bonding admixture, and FIBERMESH 150 for reinforcement.
2.2 - Sample Molding
A total of 54 specimens of 5"x5"x5" dimensions were created consiting of a 2.5" layer of concret poured onto a 2.5" layer of sandstone.
Task 3 – Data Collection
3.1 - Freeze –Thaw Cycles
The team subjected the sepcimens to a coldweather simulation using a modified version of ASTM C666.
3.2 -Splitting Test
The team subjected the specimens toi a splitting test to observe and record the behavior of the specimen at the interface based on its designated surface roughness using ASTM C496.
3.3 - Compression Testing
During the preliminary testing process the team performed compression testing of concrete to obtain its failure strength using ASTM C116.
Task 4 - Data Analysis
4.1 - Results
The team created an analytical report of the data collected from the laboratory tests.
4.2 - Statistical Analysis
The conclusions from the analysis will determined predicted results based solely on the data obtained thus far.
Task 5 - Project Management
5.1 - Team Meetings
The team met on regular weekly meeting in order to prepare for the client meetings and obtian updates on the status of the project.
5.2 - Client Meetings
The team created meet bi-weekly with the client to update the progress of the project and address any comments or concerns that the client or the team may have come across
Task 6 - Final Deliverables
6.1 - 50% Design Report
The team submitted a 50% design report halfway through the fall 2017 containing the work performed and the data collected up to that point.
6.2 - Final Report
The team submitted a final report containing the analysis of the data collected from the tests and the overall mix design interface behavior under certain conditions.
6.3 - Final Presentation
The final analysis and findings to date were presented at the 14th Annual Arizona Pavements and Materials Conference.
