COLAMIX
(Cold Mix Asphalt)

COLAMIX is Starpeco's premixed, ready-to-use cold asphalt range — combining high-quality aggregates with our own COLABINDER slow-setting emulsion. Available in bulk or 20-litre pails.

Cold Mix Technology

Asphalt Without
the Hot Plant

Cold mix asphalt is premixed, ready-to-use asphalt produced by combining graded aggregates with a slow-setting bitumen emulsion (CSS-1h / CSS-60) at ambient temperature. Unlike hot mix asphalt, no heating is required during production, transport, or application.

COLAMIX is produced at Starpeco's Kinyerezi facility and is available in three aggregate grades — each optimised for different application types, from road patching to full pavement construction.

We also provide cold asphalt paving services — our team installs COLAMIX surfaces for roads, private compounds, commercial driveways, and public infrastructure directly.

CMA in Tanzania

Starpeco's Role in
Tanzania's CMA Story

From the first cold mix asphalt road in 1998 to national standards, government partnerships, and the training of hundreds of artisans — Starpeco has been at the centre of Tanzania's cold mix revolution.

Starpeco Milestone Industry Event Regulation / Policy
1998
Industry First

First CMA Road in Tanzania

Construction of Dar es Salaam Road in Morogoro town using Cold Mix Asphalt technique — the first application of CMA technology in Tanzania, establishing a long-term performance benchmark.

2014
Starpeco Milestone

First Emulsion Plant & CMA at National Convention

Tanzania's first bitumen emulsion plant installed at Starpeco's Kinyerezi facility. Concurrently, the low usage of CMA was raised and debated at the Annual Road Convention (ARC) 2014 — putting cold mix asphalt on the national agenda.

2015
Industry Review

CMA Performance Evaluation — Morogoro

The original Dar es Salaam Road in Morogoro town was formally evaluated — confirming the long-term performance of cold mix asphalt under Tanzanian road and climate conditions.

2016
National Policy

Low Volume Road Manual Published

The Low Volume Road Manual was officially published, recommending the use of CMA for road construction and maintenance across Tanzania — a formal policy endorsement of cold mix technology at national level.

2017
Regulation

TBS Standards on Bitumen Emulsion Published

Tanzania Bureau of Standards published the national TBS standards for bitumen emulsion — formalising quality and specification requirements for emulsion-based products, including cold mix asphalt.

2018
Starpeco Milestone

MoU with University of Dar es Salaam

Starpeco signed a formal MoU with UDSM to promote and advance COLD MIX technology in Tanzania — combining academic research capability with Starpeco's industrial manufacturing and product expertise.

2019
Starpeco Milestone

UDSM Roads Built · TANROADS Partnership · East African Standards

Construction and maintenance of three UDSM campus roads using CMA technology (Namkua, Idete, and Chagongwe). East African harmonised bitumen standards approved. MoU signed between TANROADS and Starpeco — embedding cold mix into national road authority practice.

2020
Starpeco Milestone

400 Artisans Trained — Dodoma City

Training of 400 artisans in cold mix patching techniques, with live demonstration works on Samsa and Magufuli Roads in Dodoma City. CMA further applied in Municipal infrastructure across Tanzania.

2021
Starpeco Milestone

National Training with TANROADS & ZANROADS

Training and demonstration programmes conducted with Tanzania's key state regulatory bodies — TANROADS and ZANROADS — embedding cold mix asphalt as standard practice in Tanzania's national road maintenance programme.
