You could, but then you might risk causing damage to the new paving slabs, or exacerbating drainage issues. I would go ahead and remove the old slabs as these are usually just laid in with plain sand between them. Even if it's cement, I'd hate to have to do it over.

Brick paving is the use of loose bricks instead of cement or asphalt to lay down a flat surface on the ground. This is a very common landscaping technique that is popular because it looks quite nice and gives a number of other benefits over different ways of doing the same thing. Brick paving is something that anyone can use to enhance both the look and the functionality of their home. First off, brick paving is used a lot in making little paths through a yard or garden. People have done this before with either dirt or cement. Dirt is not as nice as brick paving because it requires a lot more upkeep. The dirt can get spread around or scuffed up. You frequently have to bring in more dirt to fix the problems, and so it is a never-ending process. Cement does not require very much upkeep, but it does not look as elegant and beautiful as bricks. Brick paving is also used for driveways. This is very useful because the bricks have a little space between them. They are allowed to move and shift under the weight of people and vehicles. This shifting is not enough that you can even see it, but it means that the driveway will not crack -- like asphalt and cement will do -- and have to be patched. The bricks will just move around a little bit and resist damage. This can save you a lot of money in the long run since you will not have to do any repairs. It also looks very nice for those who are driving by on the street. Finally, brick paving is used for patios. This has the same benefit that a driveway has in that the bricks can move. You may not be driving on your patio, of course, but this also keeps the bricks from breaking in the winter. Both temperature changes and ice can damage a cement patio. The bricks will have a high-class appeal to begin with that they will not lose due to damage in the colder months. This is also good if you are going to have a lot of people on the patio.
Asphalt is a petroleum based product. It is mixed with rock and it acts like a binder and when layed and compressed, it makes a smooth surface like a road. soil cement is rock mixed with portland cement with enough water added to bid it together. It's normally used as a base for a road. it's pure mineral with water.
