1.0 Introduction

This report summarizes the results of the road investigation completed for the 2019-2023 Henderson

Highway pavement renewals project. The street included Henderson Highway Southbound between

Leighton Avenue and McLeod Avenue. The investigation was carried out in accordance with the City

of Winnipeg public works street project requirements (Bid:156-2020).

2.0 Road Investigation

The investigation included coring of pavement at 10 locations. The WSP Canada Group Ltd. selected

the investigation locations as shown on Figure 01 (attached).

The pavement coring was conducted between September 24, 2020 and September 25, 2020. The

pavement (asphalt and concrete) was cored by Jashandeep Singh Bhullar of TREK Geotechnical Inc.

(TREK) using a portable coring press equipped with a hollow 150 mm diameter diamond core drill bit.

Core samples were also retrieved and logged at TREK’s material testing laboratory. A summary table

and asphalt and concrete pavement core photographs are included in Appendices A.

Two concrete cores were selected for concrete compressive strength breaks and the length to diameter

ratio ranged between 1.01 to 1.21 for the cores collected The core compressive strength tests were

tested in accordance with CSA A23.2-14C - wet condition. The measured compressive strengths were

also corrected based on an adapted ACI 214.4R-03 Standard to estimate the in-place concrete strengths

The table below summarizes the compressive strength results while the compressive strength testing

details and the correction factor methodology are included in Appendix B.

The locations noted on the summary table (Appendix A) are based on the core locations relative to the

nearest address, and measured distances from the edge of pavement or other permanent features. UTM

coordinates measured using a handheld GPS unit are also provided.

3.0 Closure

The information provided in this report is in accordance with current engineering principles and

practices (Standard of Practice). The findings of this report were based on information provided (field

investigation).
